Weathered pieces of rock are moved from one place to another during erosion.

Here's why:

* Weathering breaks down rocks into smaller pieces. This can be caused by wind, water, ice, or even plants.

* Erosion is the process of moving those weathered pieces away from their original location. This is typically done by wind, water, or glaciers.

So, weathering prepares the rock fragments, and erosion carries them away.
